Power steering reservoir cleaning improves system performance conditions and revitalizes seals, and reduces wear and noise. All car owners should know every possible method of how to clean power steering reservoir to help the car perform long. If you regularly clean the power steering reservoir, it helps to prolong the life of the power steering component by preventing internal power steering fluid leaks.

How To Clean Power Steering Reservoir

Hydraulic fluid spilled power steering fluid on the engine and is pressured by power steering motors to increase the number of forces applied on steering wheels in a system. This fluid becomes polluted over time as internal operating systems wear and hoses break down, making it darker in color and less efficient in lubricating the mechanism.

It is not wise to clean the power steering reservoir with any cleanser or detergent in this fragile engine condition. Also, these cleaners must be strong enough to remove power steering fluid stains, especially if they have been there for a long time.

This article will discuss how to remove power steering fluid from a reservoir and how to properly clean the reservoir and handle power steering fluid leaks when the car is off and refills.

Why is my power steering fluid leaking?

power steering fluid leak

Hydraulic steering fluid is pumped through hoses to the steering gear. The fluid can leak from those parts. Some steering systems incorporate coolers, which might cause leaks.

A power steering fluid leak is usually caused by worn-out seals or normal wear and tear. The colour of the power steering fluid varies widely, but it is typically red, pink, or clear. Contaminated steering fluid is typically dark or black. Insufficient fluid in a pump allows metal particles to infiltrate other steering components like the rack and gear, causing catastrophic damage.

The steering hoses can leak fluid. The high-pressure hoses might develop cracks and spilling or overfilling power steering fluid when connected to metal connections. There are also seals in the steering rack or gear that can fail, allowing fluid to leak.

You can check the power steering fluid level during the oil change period, but it can also be checked if you suspect any problem. After a few minutes of running the car, check this fluid. You can also check the fluid levels while the engine is turned off.  Also, you might need to fix your radiator in the process as well. So, keep that in mind!

What can I use for power steering fluid?

There are three kinds of cleaning process of the power steering reservoir. Among them, degreasers and pressure washers are advisable. Below are details:

Engine Degreasing Agent: 

Degreasers are one of the greatest engine cleaners. If your power steering fluid hose is leaking, you should decrease the engine. An engine degreaser will not only clean the power steering fluid but also clean the engine chambers. Few top-class degreasers are  Oil Eater AOD1G35437 (liquid base),  Chemical Guys CLD_201 16 (spray base) and Gunk FEB1  ( foam base).Let’s see how to the engine with degreasing agent:

  1. Firstly, remove any twigs or other dirt from the engine bay before cleaning it. You can use a delicate brush. 
  2. Then cover any electrical components such as cover fuses, connectors, etc and disconnect the battery before using the degreaser. Also, cover any exposed wires and spark plugs.
  3. Before degreasing, run the engine for 5 minutes. Heat makes removing grease from the engine much easier. 
  4. Then turn the engine off and apply any sort of engine degreaser, foam, spray, or liquid, but most of them act in the same way. 
  5. Soak the degreaser for 3 to 5 minutes. Then pour the engine with water from a hose and be amazed at how new it looks. 

Shampooer And Pressure Washer:

You must know how to clean power steering fluid off the engine to reduce your servicing cost. This is why pressure washers have made car washing much simpler. Continue to exert intense pressure on an engine after applying Karcher Car Wash Wax Soap. Then, it cleans the car’s washer and reservoir.

Another method is by applying some cleanser, preferably a shampoo like Adam’s Car Wash Shampoo, to the engine before using a pressure washer to remove the power steering fluid. Follow the step for doing the cleaning:

  1. First, turn off the engine of the car and cover the battery and wires.
  2. Then apply the shampoo or car wash soap to the particular place.
  3. After that use, stiff-toothed plastic bristled brushes to rub and remove the tuff stains.   
  4. Keep the soap or cleaner for 5 minutes.
  5. Afterwards, pressurize an engine with a steady stream of water. 
  6. Then turn the pressure washer off and let it dry.

Alcoholic Liquid:

Indeed the most stubborn stains can be removed with the help of rubbing alcohol. A few things to note about rubbing alcohol is degreasing it or washing it with water can cause it to ignite. Next, even though rubbing doesn’t react with aluminum alloys at room temperature, it can chew through wires and other electrical components.

We suggest using Bugsplatter and Chemical Guys SPI22016 rubbing alcohol to clean the engine when no other option exists. Following are the procedures:

  1. First, before utilizing this procedure, disconnect the battery and turn off your car.
  2. Then wipe your engine and clean it with a cloth or brush.
  3. Then take a piece of cloth and dip in some alcohol. Use only tiny amounts of this cleaning agent. Do not use rubbing alcohol directly on oil stains.
  4. As it evaporates quickly so rub the alcohol with a cloth to remove the reservoir.
